rust having a different identity than the iron it forms on
D
having less ash than the paper that was burned to form it

A physical change alters a substance’s form or state without creating a new substance. Ice melting into water is a change of state, and the water remains the same substance. Vinegar reacting with baking soda and iron rusting are chemical changes that form new substances.
